2003 CHEVROLET VENTURE Owners Manual

{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.
5. Check that the jumper cables don't have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged, too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (-) will go to a heavy,
unpainted metal engine part or to a remote
negative (-) terminal if the vehicle has one. Don't
connect positive (+) to negative (-) or you will get a
short that would damage the battery and maybe
other parts, too. And don't connect the negative (-)
cable to the negative (-) terminal on the dead
battery because this can cause sparks.
6. Connect the red positive (+) cable to the positive (+)
terminal of the dead battery. Use a remote
positive (+) terminal if the vehicle has one.7. Don't let the other end
touch metal. Connect it
to the positive (+)
terminal of the good
battery. Use a remote
positive (+) terminal
if the vehicle has one.
8. Now connect the black
negative (-) cable to
the negative (-)
terminal of the good
battery. Use a remote
negative (-) terminal
if the vehicle has one.
5-47

Don't let the other end touch anything until the next
step. The other end of the negative (-) cable
doesn'tgo to the dead battery. It goes to a heavy,
unpainted metal part, or to a remote negative (-)
terminal on the vehicle with the dead battery.
9. Connect the other end
of the negative (-)
cable at least 18 inches
(45 cm) away from
the dead battery, but
not near engine
parts that move.
The electrical connection is just as good there, and
the chance of sparks getting back to the battery
is much less.10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery. If
it won't start after a few tries, it probably needs
service.
Notice:If the jumper cables are removed in the
wrong order, electrical shorting may occur and
damage the vehicle. The repairs would not be
covered by your warranty. Remove the jumper
cables in the correct order, making sure that the
cables do not touch each other or other metal.
